We have a construction company and I am designing a program in Visual basics for it. This program is intended to be installed only on the computers in our office ( its not going to be distributed ). There is always a risk that one of our employees will take our software and distribute it . Is there anyway to prevent this. If not how can we make this as difficult as possible?

View 2 RepliesWhen I use the code Dim di As New IO.DirectoryInfo("C:")it works fine, but when i use a string variable named "infos" i.e.Dim di As New IO. DirectoryInfo(infos)which takes an input from user, it gives me an ArguementException "Illegal Characters in Path".I tried replacing the variable, checked its value in the msgbox which is fine, but the double quote is added directly when it executes the IO.DirectoryInfo line and throws an exception. (Check the attachment)I have also tried infos.Replace("""",String.Empty) to remove the possible double quote, but it still holds that double quote.And when I use the same variable "infos" with substring to get the Drive, it works fine

View 4 RepliesI am doing some url redirections in a project that I am currently working on. I am new to web development and was wondering what the best practise was to remove any illegal path characters, such as ' ? etc.I'm hoping I don't have to resort to manually replacing each character with their encoded urls.
I have tried UrlEncode and HTMLEncode, but UrlEncode doesn't cater for the ? and HTMLEncode doesn't cater for '
E.G. If I was to use the following:
Dim name As String = "Dave's gone, why?"
Dim url As String = String.Format("~/books/{0}/{1}/default.aspx", bookID, name)
Response.Redirect(url)
I've tried wrapping url like this:
Dim encodedUrl As String = Server.UrlEncode(url)
And
Dim encodedUrl As String = Server.HTMLEncode(url)

How to protect my vb project from illegal copy
View 10 Repliesi have a list box or directory paths, the program basically copies the directory to a selected destination and moves down the list to the next path and copies that path. I'm having a few problems with this, but mainly this one where the application errors out and stops completely with this error:
"Illegal characters in Path."I would really like to address this and get it resolved, or is there anyway it can report this, but move on to the next path in the ListBox?
When I run the program with maximum attempt of 3 with correct username and password, Illegal user will pop up,,,i really dont know what to do.illegal user must be pop up when i already attempt " try again " then another "3attempt" then the username or password are wrong.[code]

I know this isn't a vb.net question per se, but I hoping that somebody else out there can shed some light on my problem. I have a query that looks like this:

I am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the
system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.
temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)

What characters are illegal to use in a file path name? I tried to save a text file using a filename that had only a dash in it. I got an error that said Illegal characters in the path name. This happened when I saved it using the UTF8 and Unicode encoding methods. Also, which is better to use -- UTF8 or Unicode? Which encoding is used in Microsoft Word files?
View 2 RepliesAn interesting feature, I have seen in jDownloader software is any links I copy in the browser window (i.e., Ctrl+c), the copied content links automatically appears ( i.e., with out me actually pasting it) in their UI and starts downloading the content from the links, if they are valid.I would like to program the same but am puzzled as how to access the variable to which OS copies.
View 3 RepliesI'm looking for a way to have my code build two copies of itself at once.The program has an "A" and a "B" configuration that need to be compiled as Prog-A.exe and Prog-B.exe every time the code is compiled. I can do this manually, but I assume there's some way to do it in code? What I'd like is to use conditional compilation to have the A configuration compile so that it runs a "setup as A"-type method on load, and the B likewise, and then have it compile both versions each time.
View 1 RepliesWhat I mean is, I would like to make an exclusive program, but I don't want it falling into the hands of someone I didn't give permission to.Or perhaps make it require a password to function, and be able to change that password for all copies whenever I want.

I've a Crystal Report of one page. Only one.
I want to clone that page, so when you print that report, you get 2 copies with the same data.
I know can be done manually, but i want to avoid of setting up the printer and write "Yes!, i want 2 copies of this".
Timelines ->
NOW ->
Use software, generate Crystal, go to in-built crystal viewer print button, write '2' in copies, print.
I WANT ->
Use softwre, generate Crystal, print dialog come up (this is done), you hit 'Enter' and 2 copies will be printed (a.k.a 2 pages which are the sames)
I looked up for sub.reports but i don't want them in the same page.

I'm creating what should be a simple copy and paste type of program. Basically you put text in the textboxes and click the copy button to copy it to the clipboard.

But, after clicking the "reset" button to clear all of the text boxes for another use, I fill in the information as normal, I click the copy button and i get this popup titled "ArgumentException was unhandled" followed by the error "Illegal characters in path".
